“…Independent empirical studies have demonstrated that the cognitive capacity of hearing aid users (e.g., working memory capacity) is associated with their speech perception success ( Humes, 2002 ; Humes, Kidd, & Lentz, 2013 ; Rudner, Foo, Sundwall-Thorén, Lunner, & Rönnberg, 2008 ; Rudner, Rönnberg, & Lunner, 2011 ). In addition, hearing impairment has been associated with changes to anatomical structure ( Husain et al., 2011 ; Peele, Troiani, Grossman, & Wingfield, 2011 ), cortical plasticity in the brain ( Campbell & Sharma, 2013 ), and reduced temporal and spectral resolution ( Arlinger & Dryselius, 1990 ); these changes may also be related to behavioral speech perception outcomes of hearing aid users.…”

This study compared elderly hearing aid (EHA) users and elderly normal-hearing (ENH) individuals on identification of auditory speech stimuli (consonants, words, and final word in sentences) that were different when considering their linguistic properties. We measured the accuracy with which the target speech stimuli were identified, as well as the isolation points (IPs: the shortest duration, from onset, required to correctly identify the speech target). The relationships between working memory capacity, the IPs, and speech accuracy were also measured. Twenty-four EHA users (with mild to moderate hearing impairment) and 24 ENH individuals participated in the present study. Despite the use of their regular hearing aids, the EHA users had delayed IPs and were less accurate in identifying consonants and words compared with the ENH individuals. The EHA users also had delayed IPs for final word identification in sentences with lower predictability; however, no significant between-group difference in accuracy was observed. Finally, there were no significant between-group differences in terms of IPs or accuracy for final word identification in highly predictable sentences. Our results also showed that, among EHA users, greater working memory capacity was associated with earlier IPs and improved accuracy in consonant and word identification. Together, our findings demonstrate that the gated speech perception ability of EHA users was not at the level of ENH individuals, in terms of IPs and accuracy. In addition, gated speech perception was more cognitively demanding for EHA users than for ENH individuals in the absence of semantic context.

“…Hearing Impairment A number of previous studies have shown that sensorineural hearing impairment leads to a decline in many auditory resolution tasks (Humes, 1983 ;Tyler, 1986 ;Nelson and Freyman, 1987 ;Hall III et al, 1988 ;Arlinger and Dryselius, 1990 ;Schorn and Zwicker, 1990 ;Peters et al, 1998). The outcome of the present study in general confirms these results.…”

Temporal, spectral, and combined temporal-spectral resolution of hearing was assessed by recording masked hearing thresholds. The masker was an octave band noise. Spectral resolution was assessed by introducing a spectral gap of half an octave bandwidth in the masker. A 50–msec gap assessed temporal resolution. The spectral and temporal gaps were used separately or simultaneously. Normal-hearing and hearing-impaired subjects participated. For each masking condition, the subjects were tested at masker levels 50, 60, 70, and 80 dB SPL and at test-tone frequencies 0.5,1, 2, and 4 kHz. Normal-hearing subjects showed reduced masking with spectral and temporal gaps. The combination of spectral and temporal gap reduced masking further. The release of masking was dependent upon the masker level. Hearing-impaired subjects showed less release of masking than normal-hearing subjects. The degree of hearing impairment was inversely related to release of masking. Reliability of the test procedure was assessed.

“…There is a long history of research that has attempted to identify spectral or temporal processing impairments in listeners with hearing loss, and the consequences of those impairments for the intelligibility of speech in the presence of noise backgrounds (e.g., Elliott, 1975;Arlinger and Dryselius, 1990;Dubno and Dirks, 1990;Festen and Plomp, 1990;Schorn and Zwicker, 1990;Phillips et al, 1994;Stuart and Phillips, 1996). Recently, there has been interest in the effects specifically of the spatial separation of speech and background noise on speech intelligibility (Yost et aI, 1996;Noble et aI, 1997;Peissig and Kollmeier, 1997;Kidd et aI, 1998).…”

The Hearing-in-Noise Test (HINT) is able to measure the benefit to speech intelligibility in noise conferred when the noise masker is displaced 90 degrees in eccentricity from a speech source located at zero degrees azimuth. Both psychoacoustic and neurophysiological data suggest that the perceptual benefit of the 90-degree azimuth separation would be greatest if the speech and noise were presented in different acoustic hemifields, and would be smallest if the two sources were in the same acoustic hemifield. The present study tested this hypothesis directly in ten normal-hearing adult listeners. Using the HINT stimuli, we confirmed the hypothesis. Release from masking scores averaged 8.61 dB for "between-hemifield" conditions, 6.05 dB for HINT conditions, and 1.27 dB for "within-hemifield" conditions, even though all stimulus configurations retained a 90-degree angular separation of speech and noise. These data indicate that absolute separation of speech and noise alone is insufficient to guarantee a significant release from masking, and they suggest that what matters is the location of the stimulus elements relative to the left and right spatial perceptual channels.
